JOSEPH D. PATTON, OF TREVORTON, PENNSYLVANIA.

IMPROVEMENT IN eAs-REToRTs.

Specification forming part of Letters Patent No. 139.605, dated J une 3,1873; application filed Y April 26, 1873.

To all whom 'it may concern p Be it known that I, JOSEPH DESEA PATToN.of Trevorton, in the county of Northumberland and State of Pennsylvania,have invented a new and useful Improvement in Gas-Retort-s,

of which the following is a specification My invention consists of aretort protected from direct contact of heat by the brick-work in whichit is set, or partly by the same and partly by another retort, incombination with one or more retort-s wholly exposed to the heat of thefurnace, for gradually heating thesubsta-nce of which the gas is vto bemade; the object being to provide an arrangement whereby resin orvolatile oil can be successfully treated, which they cannot be in theordinary retorts, in which they are subjected, from the beginning, tothe intense hea-t of retorts directly exposed to the heat andsufficiently hot to convert them into iixed gas.

Fi gurel is a sectional eleva-tion of a furnace h and retorts, showin gone way of arranging the retorts according to my improvement. Fig. 2 isa sectional elevation of another arrange? ment; and Figs. 3 and 4 aresections of retorts, showing different forms adapted for my purposes. M

Similar letters of reference indicate corresponding parts. Y

In Fig. 1, A represents Aan upper retort of semicircular form, incross-section, embedded in the masonry B, and resting on an invertedretort, C, of similar form, partly embedded in outer cylinder Canswering to the retort C and the inclosing brick-work. Fig. 4is thesame as Fig. 2, except a slight moditicationin the form of the device.Any other equivalent arrangement will servethe purpose which I seek,which is to gradually heat the gas-yielding substance when resin orvolatile oils are used, which are subject to great waste on bef ing castor injected directly in a retort suiciently hot to convert them intotixed gas. rIhe arrangement is such that the oil or resin being suppliedto the protected retortA or A through pipe J will, after passing thewhole length of said protected retort, be delivered into thepartly-protected retort C or C', and thence it will gointo the retort orretorts wholly exposed to heat, where the process will be'completed, andthe gas will be expelled tol 'Ehe holder through .any suitablepipe-connecion.

'l The arrangement may also be used with good results for making gasfrom coal, suitable contrivauces being used to shit'tthe charge Athesaid protected retorts being wholly or partly inclosed by the masonry,lor partly by tie same and partly by other retorts which are partlyinclosed bythe masonry, all sub-` stantially as specified.
